Ethylene Propylene Diene Monomer (EPDM):
It has excellent heat resistance, ozone resistance, and aging resistance.
In addition, it also features high-level elasticity, good low-temperature performance, and excellent insulating properties. The applicable operating temperature range is from -45°C to +150°C (up to +175°C for short periods). For the sulfur-cured type, the range can be reduced to -45°C to +120°C (up to +150°C for short periods). It is typically used in applications involving brake fluids (based on ethylene glycol) and hot water.
Based on its properties, EPDM O-rings are commonly used in:
Automotive Industry: Cooling systems (radiator, hose seals), braking systems (brake fluid), window seals, parts of fuel vapor systems (but not in direct contact with gasoline).
HVAC (Heating, Ventilation, and Air Conditioning): Chilled/hot water systems, refrigerants (e.g., R134a) seals.
Household Appliances: Dishwashers, washing machines, water heaters, coffee makers, and other components in contact with hot water or steam.
Construction and Outdoor Equipment: Door/window seals, curtain wall seals, outdoor electrical cabinet seals, swimming pool equipment.
Others: Food and beverage equipment (resists hot water sanitation), low-pressure steam valves, some chemical processing equipment (specific acid/alkali environments).
Welcome to HOVOO, a Chinese seal factory. Production of PU, Rubber and PTFE seals. The seals include O-ring, piston seal, rod seal, Gray ring and gas seal.
